抄録

By using a conventional electron beam welding machine, an electron beam welding of Zr₅₀Cu₃₀Ni₁₀Al₁₀ bulk glassy plates has been achieved in the welding condition leading to the suppression of heat affected zone (HAZ). In order to obtain the cooling rate, which is sufficient for glass formation, the welding speed was controlled to be higher than 100 mm/s and the beam-radiated area should be limited to be smaller than 0.8 mm in diameter. Joint strength of the welded bulk glassy plate is about 1400 MPa, which is lower by 15% than the tensile strength (1650 MPa) of the glassy alloy. The fracture of the welded alloy plate occurs along shear slip plane across the welded area, reflecting good ductility in the welded area of the Zr₅₀Cu₃₀Ni₁₀Al₁₀ bulk glassy alloy.
